Re: Compilation failure with WITH_DTRACE_TESTS on mips/mips and powerpc/powerpc; it's trying to compile a host object on mips/powerpc because MAKEOBJDIRPREFIX is incorrect

Deleting the lines that pass -m32/-m64 gets me back to the same point I was at before:

dtrace: failed to link script /scratch/tmp/ngie/svn/cddl/contrib/opensolaris/cmd/dtrace/test/tst/common/json/usdt.d: incorrect ELF machine type for object file: tst.usdt.o
--- usdt.o ---
*** [usdt.o] Error code 1

I’ll need to check .PATH, but I think it’s picking up the host copy by accident:
